Minimum A2l File Requirements to read data from an ECU

[sfrosty]

What are the minimum requirements to read data from an ECU using an A2L file. I have A2L files that do not contain all the fields that are displayed when using the NI A2L file viewer. For example, I have A2L files that do not contain a complete list of Protocol, Baud Rate, Byte Order, DTO Id, CRO Id, Station Address, and Cmd Byte Order. Some A2L files I have may only contain one or two of the parameters with the rest highlighted in red. What are the minimum requirements of an A2L file regarding these parameters in order to read data from an ECU?

Almost everything in the A2L file can be overridden programmatically. For example, if the A2L doesn't specify a baud rate you can provide on with Set Property.vi before connecting to the ECU. The actual minimum set of properties is dependent on CCP/XCP protocol and communications bus type.
